[Important Notice] Changes to Login Method and Introduction of One-Time Password

Thank you very much for your continued use of our service.

As part of our ongoing efforts to protect against the rise in unauthorized access, we will be updating our login method to a One-Time Password (OTP) system, sent via email, to keep your account safer and more secure.

The one-time password system is a login method in which you enter an authentication code sent to your registered email address.
There's no password to manage, the risk of unauthorized login by third parties is greatly reduced.
Since each authentication code is valid for one-time use only, this helps prevent misuse.

・Date of Change
Wednesday, August 19, 2026, from 10:00 AM

・New Login Method
1.  Enter your email address on the login screen
2.  Click "Continue" to receive a 6-digit verification code
3.  Enter the verification code to complete the login.
*Please note that the verification code has a limited validity period.

Please note that your existing password will no longer be valid for login. Thank you for your understanding.
